othis end we place in or on the said mass a pellet of spongy platinum,andprovide means for introducing a fluid combustible to-this pellet,whereby the temperature of the latter is rapidly raised, and the heatradiated by the pellet to the adjacent or surrounding catalytic massquickl raises this mass to the temperature required for the normalworking of the apparatus. The. fuel used for the purpose described maybe a liquid, vapor or gas, for example liquid or vaporized alcohol orhydrocarbon, or

illuminating gas, pure or mixed with air, andahe same may be introducedby pressure, suction, capillarity or other convenlent means. I
